A CORPORATION OF NEW v SEALED RECEPTACLE.

To all whom it may concern Be it known that we,O'r1s E. GLIDDEN andANDREW S. N1oo, citizens of the United States, residing at Le Roy, inthe county of Genesee and State of New York, have invented new anduseful Improvements in Sealed Receptacles, of which the following is aspecification.

Our present invention relates to improvements in paper receptacles andmore especially to those of the type which are sealed and impervious tomoisture, and the primary object of the invention is to provide areceptacle, preferably in the form substantially of a bag, and composedof moisture-proof paper or material, folded in a manner to form asuitable space for the contents and to'bring all the free edges ofthepaper'or material together, the free edges of the paper or materialbeing then sealed by compression preferably' between serrated jaws whichmay be eitherheated or at normal temperature, such compression servingto intimately unite the layers of paper and to cause adhesion betweenthem, thereby effectually closing thereceptacle. It is also preferableVto crease and bendthe compressed portion of the receptacle laterally orat an angle to the body thereof and to iron the compressed portionwhereby the same has a tendency to remain inisealed condition.

A sealed and moisture-proof bag embodying the present invent-ion can bemade cheaply and readily by machinery of relatively simple construction,and the use of paste, metallic or `ther fastening means is avoided.

In the accompanying drawings z-Figure 1 is a diagram of a blank fromwhich a re oeptacle embodying the present invention may be made; Fig. 2is a perspective view of the partially folded receptacle; Fig. 3 is aperspective view of the completed receptacle; Fig. 4 represents, on anenlarged scale, a section through the sealed end of the receptacle. j

Similar parts are tlesignated.by the same reference characters in theseveral views.

Sealed packages, bags or receptacles embodying the present invention canbe made in various forms, that shown as an example in the presentinstance being in the form of a bag having a Satchel bottom, and it ismade preferably `from a blank of paraffin Specification of LettersPatent..

coated or so-called wax-paper and folded to form a rectangular bottom 1,sides 2, and ends 3, the lines 4L and 5 indicating Vthe folds between'the corners of the blank and the sides and ends respectively, thecorners of the blank being folded on the diagonal lines (S to foinisubstantially triangularly-shaped flaps composed of the sections 7 and 8which overlap and are folded against the respective sides 2 of thereceptacle, as shown in F ig. Q. In making up a bag or receptacle inthis ma nner,'the top edges of the sides 2 and ends 3 and also the topedges of all the flap sec.- tions 7 and 8 are brought together in lappedrelation around the mouth of the bag.

After the bag has been supplied with .its contents, the bag is ready tobe sealed, and

the sealing, according t'o the present invention, consists in stronglycompressing the lapping top edges of the bag whereby the wax or materialwith which the paper is coated causes a tight closure and a firmadhesion between the different layers. -The sealing ioperation ispreferably performed yby compressing the upper lapped edges of the bagbetween jaws having serrations, the projections on one jaw beingopposite to the depressions of the companion jaw, compression of thelayers of waX paper between such jaws crimping and corrugating the paperin such manner as to cause firm adhesion between the wax surfaces andforming the sevveral layers into a stifl'ened bar 9 which has apermanent set and has a tendency to maintain the edges of the bagsurrounding the lmouth thereof in closely contacting sealed condition..To assist in maintaining the bag in closed sealed condition, it ispreferable to bend the bar 9 sharply on the line 10 into an angularposition and to iron the opposed faces 11 and 12 of the. bar 9, therebyincreasing the adhesion between the layers of waxpaper composing the barand also giving a finished appearance to the exposed faces of the bar.

A sealed bag or receptacle embodying the present invention is especiallyadapted to be used within a carton, and the seal provided enables bagsor receptaoles'composed of wax paper to be closed eectually.

lVe claim as our invention 1. A sealed receptacle composed of a singlerectangular sheet of material, all the edges of the sheet being broughttogether into lapped relation about the mouth of the receptacle, themouth of the receptacle being closed and sealed by compression andindentation of the lapped edges of the material into intimate Contact.

2. A sealed receptacle composed of a sheet of material having all theedges thereof'brought together and lapped in a line across the top ofthe receptacle,y said lapped edges being compressed and formed Withinterei gaging indentations to seal the receptacle.

3. Asatchel-bottoni receptacle composed y of a single sheet of paperfolded to form a body and having all the marginal edges thereof broughttogether in lapped relation in a line extending across the top of thereceptacle, such lapped portions being coinedges of the sheetl broughttogether in-lapped relation about the mouth lof the bag7 said lappedportions being indented and compressed into intimate adhering contactand bent angularly With respect to the body ofl the bag. y
